Recovery of Data from Systems for Collecting, Storing, and Processing Information
Data collection, storage, and processing systems include: video / photo recorders (DVR, AHD, NVR), audio recorders, voice recorders, surveillance systems on disk arrays, photo / video cameras, recording and information control equipment.
To extract data from such devices, we use special methods and algorithms of our own design.
Symptoms of Malfunctions
1. Appropriate sound alerts, and the appearance of warning labels during operation.
2. The process of registration, collection, or data processing does not start.
3. Hanging in the process of recording, registering, collecting, or processing.
4. Lack of response to some commands.
Features of the Operation of Devices for Recording, Storing, and Processing Data. Causes of Malfunctions
This type of device includes:
1. Audio - video equipment in a monoblock design (video cameras, voice recorders, cameras), and built-in separate blocks - functional units (quadcopters, drones, UAVs, robots).
2. Systems of video surveillance, video recording and tracking DVR, NVR, car video recorders.
3. Autonomous and built-in means for collecting and processing parametric data (geolocators, leak detectors, gas detectors, thermal imagers, pyrometers, recorders, analyzers, sensors, etc.).
All data acquired by these devices must be stored securely. These instruments require reliable storage solutions to ensure optimal performance. For local storage of data, it is critical to have a reliable internal drive, or memory card. Many of them are connected to the Internet, or separate secure networks to provide data transfer to a cloud server, or to a secure local storage device.
Drones and UAVs move quickly and are sometimes subjected to unplanned heavy impacts. They benefit from solid-state flash drives that have no moving parts. Their work uses advances in mobile technology, built-in storage (eMMC and UFS), removable cards, and solid state drives.
There are special requirements for hard disk drives used in video surveillance systems. The disks must have an increased data rewriting resource, and hardware protection against unauthorized access attempts, and adaptation for parallel recording of several high-definition video streams.
Industrial and military systems use onboard storage in the form of single ruggedized NAND chips, onboard controller nodes (eMMC, UFS) using advanced hardware error correction techniques, and storage based on RAID arrays.
Any data store can fail. Manufacturers of data carriers do not give an absolute guarantee of the safety of information. A reliable way to store is to regularly back up files. If your device malfunctions, please contact us.
Attention! Any attempt by unqualified intervention in such a device can lead to partial or complete loss of information with the impossibility of recovering it in the future.
